A friend of ours did that, and he's lost 60 pounds. The doctor read my partner the riot act last week about his being overweight, and I shudder to think what I'm gonna hear from her at my next appointment, when she sees how obese I've also become. In my case partly due to the Lupron testosterone suppression therapy I'm undergoing.

Aside from limiting certain types of food, a major aspect is precise & consistent portion control, using a kitchen food scale as needed. I won't put links here, because I'd like to hear from guys who've actually tried it themselves, and they'll already know how you do it. Our friend's had great success, but that's one guy, and we'd both appreciate receiving additional input. Thanks.
